The Simpson ECCOQ9-SDS2.5 is an 8-3/4" Beam End Column Cap with Legs Omitted, engineered to deliver robust column-to-beam connections in end-of-beam applications on top of steel members. Designed without legs, this column cap enables field-welded attachment to steel columns and beams for maximum versatility in the field. The seat of the column cap provides additional surface area for bearing that extends beyond the side of the column, helping to distribute load from the beam and provide reliable support for the connection. Built for speed and strength, the ECCOQ9-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws for fast installation while attaching to a greater net section area of the column than a standard bolt attachment normally provides.

Frequently Asked Questions

What does "legs omitted" mean on the ECCOQ9-SDS2.5, and how does it affect installation?

The legs-omitted design means the column cap does not include pre-attached legs, which allows it to be field-welded directly to steel columns and beams. This gives installers greater versatility in the field, making the connector suitable for end-of-beam applications on top of steel members where a welded attachment is preferred or required.

What fasteners are used with the ECCOQ9-SDS2.5, and why are they preferred over standard bolts?

The ECCOQ9-SDS2.5 uses Strong-Drive SDS Heavy-Duty Connector screws. These screws deliver a lower profile than standard through bolts and attach to a greater net section area of the column compared to standard bolt attachment, resulting in a stronger and faster connection during field assembly.

What is the beam size this column cap is designed for?

The ECCOQ9-SDS2.5 is designed for use with an 8-3/4" beam. Simpson also notes that many combinations of beam and post sizes can be manufactured, so contacting Simpson directly is recommended if a configurable option is needed for a specific application.

Does the ECCOQ9-SDS2.5 include any features to assist with positioning during installation?

Yes, the ECCOQ9-SDS2.5 includes diamond holes that allow for convenient temporary fastening during installation, helping to hold the connector in place while permanent fasteners are applied. The overall design is also intended for quick installation to support efficient field assembly.
